I've got an Asus Xonar DGX soundcard.
YOUR BASKET
1 x Asus Xonar DGX 5.1 PCI-Express Sound Card with built in Headphone Amp £24.95
Total : £28.86 (includes shipping : £3.26).
I get very bad interference when using headphones. I've ruled out the front port, it still does it when plugged directly into the back of the card.
It's in the slot above my GPU, could this be the cause?
Any ideas?
